Question

What is the value of x? S *+559 W 2x–71° X-30

Answer 1

As shown in the figure :

The sum of the central angles = 360

so,

$(x+55)+(2x-71)+(x-3)+55=360$

Solve the equation for x :

$\begin{gathered} x+55+2x-71+x-3+55=360 \\ 4x+36=360 \\ 4x=360-36 \\ 4x=324 \\ \\ x=\frac{324}{4}=81 \end{gathered}$

So, the answer is : x = 81
